DETAILED DESCRIPTION OF EMBODIMENTS

[0017] For purposes of description herein, the terms upper, lower, right, left, rear, front, vertical, horizontal, and derivatives thereof shall relate to the disclosure as oriented in FIG. 1. However, it is to be understood that the disclosure may assume various alternative orientations, except where expressly specified to the contrary. It is also to be understood that the specific devices and processes illustrated in the attached drawings, and described in the following specification are simply exemplary embodiments of the inventive concepts defined in the appended claims. Hence, specific dimensions and other physical characteristics relating to the embodiments disclosed herein are not to be considered as limiting, unless the claims expressly state otherwise.

[0018] A modular mattress 10 may have two easily separable pieces. A spring coil section 12 may comprise a matrix of individually wrapped spring coils wrapped in a sturdy fabric, in a generally rectangular shape. The size of the spring coil section depends on the size of mattress being produced, and generally includes 900-2000 coils. The spring coil section 12 forms the base of the modular mattress and provides the base support for the consumer.

[0019] On top of the spring coil section 12 is a padding section 14. The padding section 14 is most responsible for the comfort of the mattress to the user. The padding section 14 is generally a polyurethane foam with a density that ranges generally from 1.5-1.8 lb./ft{circumflex over ()}3, however the foam may be more or less dense depending on the user's preferences. The polyurethane foam is then wrapped in a sturdy fabric into a rectangular shape that matches the spring coil section.

[0020] Overlaying both the spring coil section 12 and the padding section 14 is a sturdy fabric like a quilting. The quilting provides a key component of comfort because it gives a mattress its surface comfort. It also serves to secure the outermost fabric to the mattress's interior layers: the layers of foam, and other fill.

[0021] In a typical mattress the quilting overlaying the foam is sewn to the quilting overlaying the spring coils, which provides a unitary mattress to a user. Instead, in the disclosure, the two parts 12, 14 are formed and manufactured separately, each with a connecting element 40. The spring coil connecting element 42 may be on the top of the spring coil section 12, and the padding section connecting element 44 may be on the bottom of the padding section 14. The two connecting elements 42, 44 may be brought together to hold the mattress together during use. The connecting elements may then be disengaged to remove one portion or the other for replacement or cleaning.

[0022] As shown in FIG. 6, the connecting elements in an embodiment are a zipper 40. The spring coil connecting element 42 may be a first zipper half including a length of zipper teeth of a standard size and configuration. The spring coil zipper half 42 may be on the top surface 13 of the spring coil section 12, inset from the perimeter of the top surface 13 a distance. The length of the zipper is such that the zipper is disposed around the entire perimeter of the mattress. The padding section 14 has a corresponding foam section connecting element 44 which may be a second zipper section with the standard size and configuration of teeth. The size and configuration corresponds with the first zipper section 42 such that the two sections may be connected. The second zipper section 44 is disposed on the bottom portion 15 of the padding section 14, and may be inset from the perimeter of the bottom surface 15 of the padding section 14 by a corresponding distance from the perimeter. This distance may be a standard distance to provide a user with ease of replacement of either section by allowing a new section to be attached, and set such that the zipper is protected from users when the two pieces are connected by the overlay caused by the inset distance of the zipper from the perimeter of the two sections. For reference, the location of the zipper parts in one embodiment are generally shown as 122 and 124 in FIGS. 1-5. FIG. 6 shows a cross-sectional view of the zipper location inset from the perimeter of the mattress 10.

[0023] In another embodiment, the connection 40 between the two sections 12, 14 may be connected by a hook and loop connections (such as e.g. Velcro). In this embodiment, there may be sections of hook and loop connectors around the perimeter of the mattress, on the top surface 13 of the spring coil section 12 and the bottom surface 15 of the padding section 14. The connector sections may again be located in a standard fashion in order to correspond to one another, and be inset from the perimeter of the mattress to avoid snagging by a user.

[0024] In another embodiment, single attachments 40 may be used. The single attachments may include toggles (cylinder through a hoop), snaps, or straps and buckles. If single attachments are used they must be spaced appropriately. For most mattress sizes, the single attachments may be placed about 1 from the corners on each of the head, foot, right, and left sides, with and additional connector in the middle of the left and right sides , as shown in FIG. 1. For a king size mattress, an additional connector may be necessary on the head and foot sides as well. FIGS. 1-5 show how the straps and buckles may be used, but it should be known that a zipper or any other kind of connector may be used.

[0025] In still another embodiment as shown in FIGS. 7-8, the quilt portion of the padding section overlays the entire modular mattress. In other words, the padding section 14 is placed on top of the spring coil section 12 as described above. The quilt of the padding section may have an overlay 50 that reaches over the head, foot, right, and left sides of the spring coil section 12. The padding section 14 may be connected in any of the above mentioned manners, but may reach to the bottom surface of the spring coil section 12 (see FIG. 7). In this manner, a user need not find a matching fabric of the padding section when it is being replaced, but can present a new and updated outer surface of the mattress each time the padding section 14 is replaced.

[0026] Looking at FIG. 7, this overlay 50 may be attached to the bottom surface of the spring coil section 12 at a distance inset from the perimeter of the bottom surface as described above. The connector may also be attached along the sides of the spring coil section near the bottom. The overlay may also cover the zipper by approximately 1, offering cover for the zipper to prevent damage to the zipper or to prevent a user from snagging on the zipper. Covering the zipper, which includes some amount of material that the teeth of the zipper connect to, may also help in the fire resistance of the mattress, by covering the zipper material with the fire retardant quilting material.

[0027] In another embodiment as shown in FIG. 8, an overlay 50 similar to the above is used, but does not reach down completely over the spring coil section 12. For instance, the overlay may reach 3 down from the top surface of the spring coil section. In this case the zipper 40 may be placed about 2 down from the top surface 13 of the spring coil section, in order to provide about 1 of overlay 50 over the zipper 40 to protect the zipper and users from snagging the zipper.

[0028] It will be understood by one having ordinary skill in the art that construction of the described disclosure and other components is not limited to any specific material. Other exemplary embodiments of the disclosure disclosed herein may be formed from a wide variety of materials, unless described otherwise herein.

[0029] For purposes of this disclosure, the term coupled (in all of its forms, couple, coupling, coupled, etc.) generally means the joining of two components (electrical or mechanical) directly or indirectly to one another. Such joining may be stationary in nature or movable in nature. Such joining may be achieved with the two components (electrical or mechanical) and any additional intermediate members being integrally formed as a single unitary body with one another or with the two components. Such joining may be permanent in nature or may be removable or releasable in nature unless otherwise stated.
